To all whom it may c0nccm.'

Be it known that I, FREDERICK M. BALD- WIN, a citizen of the UnitedStates, residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented a new and useful Oil-Cloth-Cutting Machine,of which the following is a specification.

My invention relates to oil cloth cutting machines, being moreparticularly a table upon which oil cloth and articles of similarcharacteristics, such as paper,cloth and the like, may be cut intodesired lengths, and one of the principal objects of my invention is toproduce a machine of the character described, of simple form andconstruction in which the oil cloth may be placed upon a table in a rolland pulled out on the table to the required length, such length beingindicated by an indicator for that purpose, and the oil cloth cut asdesired. h

Other objects and advantages will appear hereinafter from the followingspecification.

Referring to the drawings, which are for illustrative purposes only, I

One edge of the oil cloth inclicated at 30 passesunder a roller '31 mounted in the box 26 and connected to the countingmechanism, being engaged between such roller and smaller rolle'rs32mounted in the table top. The oil cloth passing between such rollersrotates the-roller 31 which imparts movement to the arrow 28 through thecounting mechanism therebydndicating the amount of oil cloth pulledunder the roller 31. g

The boXJ26 hinged as indicated at 33 to any suitable support or to thetable andis provided with a stud 34 on one side thereof which is engagedby a loop 35 formed in one end ola rod 36,-.such' rod being con nectedto the short end 37 of a stop 88 pivsteam 39. to the table top, suchstop 38 having a toe 40 formed upon the outer end The oil cloth to bemeasured box 26 having been moved into the dotted line position'show n F6, which move ment oi the box swings the stop 38 into the dotted lineposition shown in Fig. 5, the toe 40 of the stop extending forwardly onthe table to approximately the line upon which the oil cloth is finallycut, or in other words, into the path of the cutters hereinaftercescribed; The free end of the oil cloth is pulled forwardly over therollers 32 until it strikes the toe 40 of the stop 38 when in the dottedline position shown in Fig.

5, whereupon the box 26 is moved down to full line position with theroller 31 in en'- tends into the open ends of the end pieces and 44, theend piece 43 being slotted as indicated at 46 and the roller havinga pin47 thereon which extends into the slot 46. Behind the end of the rollerin the end piece 43 is a coiled spring 48 which elastically holds theroller 45 in the end piece 44, but allowing for the length of the roller42 to be varied. The end pieces 43 and 44 are each provided with a spur50 received in sockets 51 on the ends of shafts 52 and 53. The shaft 53is mounted in a housing 54, this shaft being provided with a gear 55which meshes with a gear on a shaft 57, the housing 54 being secured tothe table in any suitable manner. The shaft 52 is mounted in a housing58 and is also pro vided' with a gear '59 which meshes with a gear 60 onthe shaft 57, such shaft 57 being square in cross-sectionfor thepurposes here- 'inafter described and the gear 60 being slidably mountedupon the square portion of the shaft 57 with an extension 61 having arecess 62 out therein to receive the lower portion of the front angleiron 20 of the table, being arrangedso that the housing will slidethereon and prevent the housing from tilting out 7 of position on thehub 63 of the gear 60 which forms a support for the housing One end 64of the shaft 57 is rounded and 1S mounted 1n a bracket 65 secured to thetable in any suitable manner On the inner Side of the gear 55 and thegear 59is mounted a circular plate '67, such circular mounted on a pin71 to the gears and 59,

such arms being elastically held apart by means of a coiled spring 72placed between the upper ends of the same. The arms are provided withhalf round lugs 73 which extend forwardly to receive the end of the oilcloth thereon, the end of the oil cloth being passed between the lugs'73and the extension 69 when the arms 70 are in collapsed position due topressure exerted on the arms by the fingers of the operator. When suchpressure is removed the arms operation of the handle 75 is disconti Thehousing 58 is provided the plates 8.; and

assume the position shown in Fig. 10 in which position the lug 73 on onearm engages the end of the oil cloth between such lug 73 and the fixedextension or clamping .member 69, lifter the oil cloth is so attachedthe oil cloth is drawn forward by the operation of a handle 75 mountedon the I end of the shaft 57. The shaft'57 has a hollow housing 7 6formed thereon, one end 77 of which abuts against the end of a hub 78formed on thevgear 69. The housing 76 has a coiled spring 79 therein,one end of which abuts against the end of the housing 7 I and the otherend against a flange 80 formed on the shaft 57, such spring tending tohols wardly and the narrow width of oil ClOill attached to the clampingdevice that such clamping device holds the housing 58 in the inwardposition until the cutting operation is accomplished. The operator windsthe Oll cloth upon the roller 42 until the arrow 28 indicates upon thedial 27 the amount of oil clot-h desired to be cut, whereupon the nuedand the cutting operation accomplished.

This cutting operation is performed by a cutter generally indicated at1.7, which travels across the front portion of the table between theangle iron 20 and a larger angle iron 82 which together form the knifecarriage or cutter guide, such angle iron 82 also supporting the-forwardportion of the table indicated at 83. The knife carrn comprises a rearplate 84, a front plate secured to the rear plate in any suitablemanner, the rear plate having a rearwardly extending flange 86 uponwhich is mounted a roller 87, a shaft 88 being provided for thispurpose, which extends through a bottom plate 89. A similar roller 90 isprovided to engage the side of the guide 82, such roller 90 beingmounted on a shaft 91 on the plate 89- as clearly shown in Fig. 7.Mounted in are shafts 92 and 93, the shaft 92 being above the face ofthe table and the shaft 93 being below the face of the same, such shaftshaving; shoulders formed thereon and being riveted overthe housing tingdisk 100 having a fiat face which is overlapped by the flat face of acutting disk 101 mounted on the gear 95, the disk 101 being elasticallyheld against the face of the disk 100 by a disk spring 102 clearly shownin Fig. 7. It will be noticed that the cutting disks move in thedirection of the rows indicated at 103 in 8 and that the meeting pointindicated at 1042 or" the cutter is slightly above the face of the tableso that the oil cloth will be cut as the knife carriage is moved acrossthe face of the table by the I mechanism hereinafter described.

The mechanism for operating the knife carriage consists of a series oflinks, arms and levers so arranged that a great length of travel of thecutter is accomplished with the operating mechanism confined within avery compact area. lPivotally connected to the under side of the knifecarriage by means of a bolt 105 is an outer telescoping member 106arranged to receive an inner telescoping member 107 consisting of red,one end of which is freely slidable in the member 106 and the other endof which is pivotally mounted at 108 to the rear portion of the f 'ameof the table. 109, 110 and 111 indicate brackets secured to the frame ofthe table, the bracket 110 having pivotally mounted thereon a primary orcentral arm 112. The brackets 109 and 111 have pivotally mounted thereonrespectively, ondary or side arms 113 and 11 1. The outer end of thesecondary arm 113 is pivotally connected through the medium of a link115 to the telescoping member 106 and. the outer end 01 the arm 11 1- ispivotally con nected to the telescoping member 106 by a link 116, thelinks 115 and 116 being both pivotally mounted upon a pin 11? mounted onthe member 106. The outer end of the central or primary arm 112 isprovided with a stud or belt 118, which bolt pas. as through a slot 119in a link 120, the other end oi which is pivotally mounted 121 on theside arm 113. The stud 118 also extend. through a slot 122' formed inone end of a link 1233, the other end of such link being pivotallyconnected at 12 1 to the arm 11%.

125 designates an operation lever which is operated at the side of thetable, being pivotally mounted to the table by means of pin or stud 126.The operating lever 125 is connected by means of a connecting rod 12"?with the central arm 112, such connection being made by means of a pin128 mounted upon the arm 112 approximately centrally of its length. Theoperating lever 125 is provided with a handle 130 which is formed bybending one end of the operating lever outwardly as shown in 2. A.support is provided for the'connecting rod 127 which consists of a h 131which is W a F 1 W mounted u on -e lfii. e oi we ti-ple by means of aclip 132.

table.

The above operating mechanism operates as follows:

By swinging the operating lever 125 from the full line position shown inFig. 2 to the dotted line position the connecting rod 127 swings theprimary arm 112 from the full to the dotted line position. Such movementof the primary arm pulls the link 120, and through the medium of suchlink operates the side arm 113 which in turn, through link 115, operatesthe member 106. The member 106 telescopes with the member 107 and movesinto the dotted line position shown, thereby drawing the knife carriageacross the table and cutting the oil cloth. 7

The knife carriage .is returi'ied by moving the operating lever backinto the full line position shown, in which case the primary arm 112operates link 1.23 which in turn operates the side arm 11 1, and throughlink 116 pushes member 106 back into the full line position ready foranother cutting operation.

Means are provided also for holding down the oil cloth adjacent to theline of cutting, such means comprising a holding finger 13st at one endof the table and holding fingers 135 and 136 at the opposite end of thetable. The finger 134 is mounted upon a shaft 137, the shaft 137 beingsupported. in a bracket 138 on one side of the table. Mounted upon thebracket 138 by means of a stud or pin 139 is a locking arm 140, one endof which is curved outwardly and upwardly to the outside of the handle130 of the operating lever, as shown in Fig. 3, such end being providedwith a knob 141. The other end of the locking arm M0 is pivotallyconnected by means 01 a stud or pin 142 with one end of a red 1413 whichrod 141-3 operates the fingers 135 and 136 through the mechanismhereinafter described. V

The locking arm 1 10 operates the shaft 137 through the medium of link14h one end of which is secured to the shaft 137 and the other end ofwhich is secured to the stud or pin 1412. The rod 143 at its other endis connected to one end oi": a rocker arm 1415, such rocker arm beingpivotally mounted on'a bracket 146 to oneside of the The other end ofthe rocker arm 1 15 is connected by means of a link 14.7 with an shaftbeing journaled upon the .frzirneo'f the machine and having mounted onone end thereof fingers 135 and 136, the shaft between such fingersbeing l in t shape as indicated at 150 in p to allow for passage of theknife ca between such fingers, it being and the fingers 135 and 136press upon theoil cloth on each side of the cutting line. The lock ingarm 14-0 is arr; d so t the ing lever 125 cannot be operated 1 holdingfingers 134i, 135 and 136 are moved arm 1.4-8 mounted upon a shart 1 19,such v release the oil'cloth such springs acting re-.

into engagement with the oil cloth, the looking' arm,when bringing thefingers to such engaging position, moving into the dotted line positionshown in Fig. 3 thereby clearing the path of the handle of'the operatinglever 125. Elastic means are provided for holding the locking arm .inthe path of the handle of the operating lever, which consist of a spring151 which operates upon the rocker arm 1 15 to place an elastic tensionupon the same and transmit such elastic tension through the rod 143 tothe locking arm.

The box 26 is preferably elastically held in lower position so that theroller frictionally engages the oil-cloth. This is accomplished bymounting a leaf spring 155 on the end of the box 26 arranged to engage arod 156 mounted on the table of the machine, such spring 155 swingingunder the rod when the box is moved to upright position.

In the form of cutters shown in Fig. 12, two sets of cutters 158 and 159are driven through the medium of gears 160, such gears being driven bythe rack 99. lVith this form of cutting device the material may be cutby drawing the cutters in one direction in which one set of cuttersperform the cutting operation after which the material may be drawn outand another length cut by moving the cutters in the opposite direction,cutting the material by the other cutters.

By using my machine in the manner above described it will be readilyunderstood that oil cloth, paper or similar articles commonly handled inrolls may be readily cut and dis pensed with accuracy and despatch. itis understood that the oil cloth after being wound upon the roller 12may be easily removed therefrom by removing the roll from its supportingmechanism and the roil slipped out of the cloth wound thereon, it beingunderstood that a wooden roller may be used in place of the collapsibleroller shown and described, such wooden roller being of the typecommonlyused for'shipping small quantities of oil cloth rolled thereon,in which case the roller would re main in the oil cloth.

The springs A8 and 79 have an additional function to that heretoforedescribed, namely, when the fingers are pressed together to spectivelyagainst the shaft 52 and housing 76 return the housing 58 to itsoriginal position.

While I have shown and described my invention as applicable to cuttingoil cloth it is to be understood that I do not limit my invention tosuch use but it can be used for handling all flexible material whethercloth. paper or similar articles.
